Jinko Solar Tiger Neo 66HL4M-BDV 620W N-type Bifacial
The Jinko Solar Tiger Neo 66HL4M-BDV 620W is a modern N-type TOPCon bifacial glass-glass photovoltaic module designed for high-performance commercial and ground-mounted installations, offering 620 W power, 22.95% efficiency, high mechanical strength, and low long-term power degradation.

Practical benefits:

• More energy from a single module: 620 W power and 22.95% efficiency reduce the number of panels needed to reach the desired system capacity.
• Additional energy from the rear side: the bifacial design uses reflected light from the ground, increasing total energy production and helping reduce LCOE; under BNPI conditions, the 620 W version can reach up to 685 W.
• Better performance under low sunlight: N-type TOPCon technology reduces LID/LeTID degradation and improves partial-light performance.
• Higher reliability: HOT 3.0, SMBB technologies, and guaranteed PID resistance support long-term durability and parameter stability.
• High mechanical strength: tested for 5400 Pa front load and 2400 Pa rear load, suitable for harsh weather conditions.

Installation notes:

• Module dimensions 2382 × 1134 mm, weight 32.4 kg — check mounting structure and transport/logistics before purchase.
• Works best where the rear side can use reflected light, e.g., on the ground or a suitable support structure.
• Electrical parameters, especially Voc 49.08 V and max system voltage 1500 V, must be considered when designing strings and choosing an inverter.

Who this module is for:

• Investors seeking a 620 W module for PV farms, commercial installations, and large rooftop systems.
• Projects that can benefit from bifacial design to increase total energy yield.
• Customers prioritizing N-type technology, high durability, and stable energy production over many years.
